How do I do an egglocke using a text file?

Sooo, I was going to do an egglocke in Insurgence with my own text. But when I opened the “egglocke testing” file, I didn’t understand a single thing, Can someone please tell me what does everything from that text means?

Go to the main menu and choose “generate egg”. It is very buggy though and crashes often.

Thank you! I really hope it doesn’t bug tho.
